“…A lowered resting orthostatic tolerance has been observed in young highly trained athletes (Levine et al 1991;Raven and Pawelczyk 1993;Ogoh et al 2003), as outlined by the statement ''trained men can run but they cannot stand'' (Greenleaf et al 1981). Others have found orthostatic tolerance to be unchanged (Hernandez et al 2005) or even improved in young highly trained individuals (Convertino 1993;Winker et al 2005). Similar work comparing young and older trained and untrained individuals found no differences in orthostatic tolerance between groups (Hernandez and Franke 2004;Franke et al 2006).…”

The cardiovascular benefits of exercise are well known. In contrast, the impact of lifelong endurance exercise is less well understood. Long-term high-intensity endurance exercise is associated with changes in cardiac morphology together with electrocardiographic alterations that are believed to be physiologic in nature. Recent data however has suggested a number of deleterious adaptive changes in cardiac structure, function and electrical activity, together with peripheral and cerebral vascular structure and function. This review serves to detail knowledge in relation to; (1) Cardiac structure and function in veteran endurance athletes focusing on the differentiation of physiological and pathological changes in cardiac remodelling; (2) Cardiac electrical activity and the veteran endurance athlete with attention to arrhythmias, the substrate for arrhythmia generation and the clinical significance of such arrhythmias; (3) Peripheral and cerebral vascular structure and function in ageing and endurance-trained individuals; and (4) directions for future research.
